TRIAGE — Rank registered books by cosine similarity to a project
AI agents call triage_books to retrieve information from Iconsult MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a retrieval and ranking operation (Read category). The tool queries a knowledge base to find books similar to a project context and returns ranked results. There are no side effects, no data modification, no code execution, no deletion, and no financial implications. The severity is low because misuse would only return irrelevant recommendations, causing no harm.
From the tool's definition Tool name and description indicate it 'Rank[s] registered books by cosine similarity to a project' — a search/ranking operation that retrieves and orders existing data without modifying it.
Documented attack patterns abuse exactly the kind of access triage_books gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Iconsult MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for triage_books:
{
"version": "1",
"default": "deny",
"tools": {
"triage_books": {}
}
}triage_books is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

TRIAGE — Rank registered books by cosine similarity to a project. It is categorised as a Read tool in the Iconsult MCP MCP Server, which means it retrieves data without modifying state.
Register the Iconsult MCP server in PolicyLayer and add a rule for triage_books: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Iconsult MCP. Nothing to install.
triage_books is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the triage_books rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for triage_books. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
triage_books is provided by the Iconsult MCP server (marcus-waldman/iconsult_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Iconsult MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
